Optional Output Cards
The TTM 01-G has a slot for one I/O card, to allow a variety of user interfaces. Each card is limited to one
additional port with at least 3 kV isolation from the rest of the system to avoid current loops.
Table 5 below shows the orderable options:
Output Type
Features
None
No optional output. These screw clamps will be blanked off on units that have no optional
output.
TTL
TTL (5 V, 150 mA) IRIG-B (B00x, B22x), DCF77 or user defined pulse output.
Serial
RS232 level (9 V, 10 mA) output supporting serial strings.
AM IRIG-B
Amplitude Modulated (AM) IRIG-B (B12x) signal, typically 8 V with 3:1 mark space ratio.
Output Impedance 120 Ω. Requires
a 100 –
180 Ω terminator.
